Description

Technical Field

[0001] The invention belongs to the technical field of industrial production, and in particular relates to a cooling tower and a liquid collecting device thereof. Background Art

[0002] In industrial production, energy supply, and large-scale building air conditioning systems, cooling towers, as key heat exchange equipment, can achieve heat exchange between hot water and air, reduce water temperature to promote water recycling, improve energy efficiency, and reduce costs. However, traditional cooling tower design and operation have shortcomings:

[0003] Single cooling method: Existing cooling towers are categorized as either dry or wet cooling. Wet cooling utilizes direct contact between water and air, removing heat through the evaporation of water. Dry cooling achieves cooling through indirect contact between air and a heat exchanger (such as a pipe). Because it's difficult to flexibly switch cooling modes, dry cooling lacks direct contact between water and air at high temperatures, resulting in low cooling efficiency. At lower temperatures, the water vapor generated by direct contact between water and air easily condenses into mist due to the low ambient temperature, creating a visual impact on the surrounding environment.

[0004] Inflexible ventilation control: The simple ventilation structure makes it difficult to open and close ventilation channels and adjust ventilation volume. Excessive ventilation at low temperatures wastes energy, while insufficient ventilation at high temperatures affects cooling. Dust easily accumulates in ventilation channels, and the lack of effective cleaning and adjustment mechanisms compromises ventilation efficiency.

[0005] Poor water distribution and collection: Uneven water distribution results in uneven cooling effect; water droplets easily adhere to structural components to form scale, reducing cooling efficiency and increasing maintenance difficulty; water is prone to leakage and splashing during collection, wasting water resources.

[0006] Difficult to meet new requirements: Under the requirements of energy conservation, emission reduction and environmental protection, traditional cooling towers have limitations in energy utilization, water conservation and environmental protection, and are unable to meet the needs of modern industry and construction for high-efficiency, energy-saving and environmentally friendly cooling equipment.

[0007] In order to solve the above problems, a cooling tower and a liquid collecting device thereof are proposed to solve the problems of low cooling efficiency and inability to select dry cooling or wet cooling in traditional devices. Summary of the Invention

One end of the connecting rod is fixed to several of the ventilation plates, and the other end of the connecting rod is fixed to a sliding block, and the sliding block is in contact with and slides against the inner wall of the curved surface of the collection box. A through groove 1 and a through groove 2 are provided on the sliding block, and the through groove 1 passes through the sliding block and communicates with the inside of the collection box.

[0025] Water sprayed from the water inlet partially enters the flow pipe, where it comes into contact with the wind from below. The wind diffuses the water in all directions, and the diffused wind exits the flow pipe through tuyere 1 and tuyere 2 and falls toward the manifold. This design ensures full contact between wind and water within the flow pipe, further enhancing the cooling effect. At the same time, the wind also helps the water exit the flow pipe, improving water circulation efficiency.

[0026] The device can operate in different cooling modes depending on temperature. At high temperatures, it uses a wet cooling mode that combines spraying and ventilation, while at low temperatures, it switches to a dry cooling mode with water flowing through the flow pipe connected to the water outlet. This multi-mode operation adapts to different ambient temperatures and cooling needs, improving the cooling tower's applicability and energy efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] There are two sliding rods 105 slidingly connected in the sealing box 104. The two sliding rods 105 are symmetrical based on the center of the sealing box 104. One end of the two sliding rods 105 is connected to the output end of the cylinder 103 to form a sealed chamber 106. The cylinder 103 does work to compress the space in the sealed chamber 106, thereby pushing the two sliding rods 105 to move.

[0049] It should be noted that: a sealing plug 1031 is fixed on the output end of the cylinder 103, and a sealing plug 2 1051 is fixed on one end of the two sliding rods 105 located in the sealing box 104.

[0053] A plurality of flow pipes 109 are fixed above the second water storage tank 108 , and the positions and numbers of the plurality of flow pipes 109 correspond to those of the water delivery ports 102 .

[0054] An air hole 309 is provided on the curved surface of the collection box 3, and the air hole 309 does not contact the water flow port 111. A connecting rod 305 is rotatably connected in the collection box 3. The connecting rod 305 is L-shaped. One end of the connecting rod 305 is fixed to the ventilation plates 302, and the other end of the connecting rod 305 is fixed to a sliding block 306. The sliding block 306 is attached to and slides against the inner wall of the curved surface of the collection box 3. A through slot 1 307 and a through slot 2 308 are provided. The through slot 1 307 passes through the sliding block 306 and communicates with the inside of the collection box 3. The through slot 1 307 is adapted to the caliber of the water flow port 111 and is located on its sliding path. The through slot 2 308 extends on one side of the through slot 1 307, with one end communicating with the through slot 1 307 and the other end adapted to the caliber of the air hole 309. The through slot 2 308 is located on the sliding path of the air hole 309.

[0055] When the sliding block 306 slides, when the through groove 1 307 is in communication with the water flow port 111 , the through groove 2 308 is not in communication with the air hole 309 ; when the through groove 2 308 is in communication with the air hole 309 , the through groove 1 307 is not in communication with the water flow port 111 .

[0056] It should be supplemented that: the connecting rod 305 is rotatably connected to the second sliding rod 310 at the bent portion, and the other end of the second sliding rod 310 is slidably connected to the inner wall of the collection box 3 opposite to the ventilation plate 302.

[0057] like Figure 3 and Figure 5 As shown, in some embodiments, a diverter plate 113 is provided between the flow pipe 109 and the water inlet 102, and the diverter plate 113 is fixed to the inner wall of the tower body 1. The upper end surface of the diverter plate 113 is provided with a plurality of ventilation holes 1136, and the inner wall of the ventilation hole 1136 is provided with an air inlet 1131, and each of the air inlets 1131 connects two adjacent ventilation holes 1136.

[0058] like Figure 6-10 As shown, in some embodiments, a sliding plate 1135 is slidably connected below the diverter plate 113 , and a spring 1137 is fixed between the diverter plate 113 and the sliding plate 1135 .

[0059] A second ventilation hole 11351 is provided on the upper end surface of the sliding plate 1135, and the position of the second ventilation hole 11351 corresponds to the first ventilation hole 1136. A conical cylinder 114 is fixed in the first ventilation hole 1136, and a guide spiral 1141 is fixed on the inner wall of the conical cylinder 114. The guide spiral 1141 is used to guide the direction of the gas.

[0060] The surface of the diverter plate 113 is further provided with fixing holes 1138 , the positions of the fixing holes 1138 correspond to the positions and numbers of the water inlets 102 , an external flow pipe 112 is fixed in the fixing holes 1138 , and an air outlet 2 1121 is provided on the outer diameter of the external flow pipe 112 .

[0061] The interior of the outer through-flow duct 112 is clearance-matched with the through-flow duct 109 , and a plurality of tuyere 1s 1091 are opened on the outer diameter of the through-flow duct 109 , and the plurality of tuyere 1s 1091 are located on the sliding path of the tuyere 2 1121 .

[0062] A mounting seat 11352 is fixed below the sliding plate 1135. The mounting seat 11352 has a mounting slot 11353 near the side of the external through-flow duct 112. A force rod 1133 is fixed to the bottom of the mounting slot 11353. A force block 1132 is fixed to the other end of the force rod 1133. A second spring 1134 is fixed between the force block 1132 and the mounting slot 11353. The second spring 1134 is sleeved on the outer diameter of the force rod 1133. During the upward movement of the through-flow duct 109, the first air outlet 1091 and the second air outlet 1121 gradually become misaligned. The through-flow duct 109 lifts the force block 1132 and the force rod 1133. The force rod 1133 drives the sliding plate 1135 to slide and cause vibration, further shaking off the water attached to the surface of the diverter plate 113.

[0063] A wind box 4 is fixed on the outside of the tower body 1 , and the position of the wind box 4 corresponds to the position of the collection box 3 . A fan 401 is fixed on the wind box 4 , and the fan 401 is used for supplying air.

[0064] Working principle:

[0065] When the temperature is high, the water to be cooled is transferred to the water storage tank 101 by starting the water pump 2, and sprayed out through the water delivery port 102 at the bottom of the water storage tank 101, so that the water to be cooled directly contacts the air and increases the contact area with the air, thereby improving the cooling efficiency of the water.

[0066] At the same time, by starting the cylinder 103, the cylinder 103 drives the sealing plug 1031 to slide downward in the sealed chamber 106, and drives the sliding rod 105 to move in the opposite direction of the collection box 3 under the action of air pressure, and drives the ventilation plate 302 to rotate. Through the rotation of the ventilation plate 302, the bellows 4 and the collection box 3 are connected through the ventilation channel 301. During the rotation of the ventilation plate 302, the ventilation plate 302 drives the sliding block 306 to slide through the connecting rod 305 until the through groove 307 is connected to the water flow port 111. The air hole 309 enables the collection box 3 to communicate with the interior of the tower body 1 due to the sliding of the sliding block 306.

[0067] By starting the fan 401, the fan 401 ventilates the wind box 4 and the collection box 3, and a part of the wind in the collection box 3 enters the interior of the water storage tank 2 108 through the through groove 1 307 and the water flow port 111, and circulates inside the water storage tank 2 108, and enters the internal space of the tower body 1 located above the diverter plate 113 through the flow pipe 109, the air outlet 1 1091 and the air outlet 2 1121. Another part of the wind in the collection box 3 enters the internal space of the tower body 1 located below the diverter plate 113 through the air hole 309.

[0068] Part of the water sprayed from the water delivery port 102 enters the flow pipe 109 under the action of gravity, and the other part directly falls onto the diverter plate 113 .

[0069] The water entering the flow duct 109 comes into contact with the wind from bottom to top, and the water diffuses to the surroundings under the action of the wind. The diffused wind is discharged from the flow duct 109 through the air outlet 1 1091 and the air outlet 2 1121 and falls onto the diverter plate 113.

[0070] The wind below the diverter plate 113 flows upward through the conical cylinder 114 and forms a wind roll through the guide spiral 1141, cooling the water on the diverter plate 113 while helping the water to fall to the liquid collecting tank 5 through the conical cylinder 114.

[0071] At this time, the direction of the wind in the conical cylinder 114 spirals upward along the direction of the guide spiral 1141, and enters the interior of the flow duct 109 through the air inlet 1131, the air outlet 1091 and the air outlet 2 1121. Since the direction of the wind entering the flow duct 109 through the air inlet 1131, the air outlet 1091 and the air outlet 2 1121 is toward the axis of the flow duct 109, the moving direction of the residual water in the flow duct 109 is further changed, helping the water in the flow duct 109 to be discharged from the outside of the flow duct 109 to complete the cooling.

[0072] When the temperature is low, the rotation angle of the ventilation plate 302 is further increased by starting the water pump 2, and the ventilation plate 302 drives the sliding block 306 to slide further, and the through groove 2 308 is connected to the water flow port 111. At this time, the through groove 1 307 is located outside the collection box 3.

[0073] By starting the second cylinder 107 , the second water storage tank 108 is driven to move upward, and the second water storage tank 108 drives the flow pipe 109 to move upward until the flow pipe 109 is connected to the water delivery port 102 .

[0074] During the upward movement of the flow duct 109, the air outlet 1 1091 and the air outlet 2 1121 are gradually misaligned, and the flow duct 109 lifts the force block 1132 and the force rod 1133. The force rod 1133 drives the sliding plate 1135 to slide and causes vibration, further shaking off the water attached to the surface of the diverter plate 113.

[0075] When the flow pipe 109 is connected to the water inlet 102, the air outlet 1091 and the air outlet 2 1121 are completely misaligned. By starting the water pump 2, the water to be cooled is transferred to the water storage tank 1 101. The water in the water storage tank 1 101 enters the water storage tank 2 108 through the flow pipe 109. The water in the water storage tank 2 108 enters the through slot 2 308 through the water flow port 111. Since the through slot 2 308 is connected to the through slot 1 307 and the through slot 1 307 is located on the outside of the collection box 3, the water in the through slot 2 308 flows out of the collection box 3 through the through slot 1 307 and enters the liquid collecting tank 5 under the action of gravity, completing the cooling.
